Abstract: A vibrating mesh nebuliser. The nebuliser (100, 400, 500) comprises a cartridge section (110, 420, 520) comprising a reservoir (180) containing a liquid to be nebulised (190), a mouthpiece comprising a conduit (160), wherein a flow path (210) is defined between the reservoir (180) and the conduit (160) and whereby a user may inhale nebulised liquid from the mouthpiece through the conduit (160). The nebuliser further comprises a body section (120, 410, 510), releasably connectable to the cartridge section (110, 420, 520) and a mesh section (530) comprising a vibratable mesh (250, 540), the vibratable mesh (250, 540) being disposable in the flow path (210), so as to nebulise liquid drawn from the reservoir to the conduit in the mouthpiece. Also provided are an apparatus and method for monitoring one or more physiological responses to material self-administered by a user.

Abstract: A mesh for use in a mesh nebuliser. The mesh 300 comprises a first plurality of apertures 310 extending through the mesh 300, the first plurality of apertures 310 having a first average diameter and a second plurality of apertures 320 extending through the mesh 300, the second plurality of apertures 320 having a second average diameter. The first average diameter is different to the second average diameter. The first average diameter may be sized to produce droplet of 1-5 ?m, whereas the second average diameter may be sized to produce droplets of 5-30 ?m. There is also provided a mesh nebuliser having the present mesh.

Abstract: A hair dryer (10) has a hand-held housing comprising an air inlet (12), an air outlet (14), a motor (1) between said air inlet (12) and said air outlet (14) to draw air in from said air inlet (12) and drive air out from said air outlet (14). A heating element (17) is located in said air flow between said air inlet (12) and said air outlet (14). The hair dryer (10) further comprises a filter on said air inlet (12). The filter comprises a metal filter plate (20) bearing a plurality of holes, wherein at least some of said holes have a maximum lateral dimension of less than 1.5 mm and wherein vertical walls of said holes through a thickness of said filter plate are substantially straight or at least partially concave.

Abstract: A shoulder assembly for connecting two arms of a hair styling apparatus, the shoulder assembly comprising: a housing; a first coupling member which is attached to the housing and which projects from the housing to couple the housing to a first arm; a second coupling member which is attached to the housing and which projects from the housing to couple the housing to a second arm; wherein both the first and second coupling members are flexible so that the first arm is movable relative to the second arm when the shoulder assembly is connected to the first and second arms.
